[BUG]: mutations and print related

[rd4com]

Bug description

Ok, because Jeff ask for bug reports in the Q/A :p

fn get_copy(borrowed p:object)->object:
    return p

fn main() raises:
    var o:object=object(Attr("value",None))

    var p = get_copy(o)

    p.value = 2
    print(o)        #mutated (i think it is quite cool and ruby like, but dont know if it is expected behaviour)

    #p.value = p 
    #print(o)       #infinite loop at runtime (Segmentation fault (core dumped)), comptime don't complain

i think those builtin lightweight objects are fantastic, it is quite cool to have those dynamic features. especially in the future use cases of wasm and where size matter in general like micro controllers. they can speed up productivity when speed is not required, like prototyping. is there any roadmap for them ? is it ok to use them ? keep up the good work

Steps to reproduce

• nothing special to do, it is is in the description

System information

- ubuntu
- mojo 0.3.0

Thanks for filing @rd4com ! This looks like infinite recursion in the print indeed. I can go add a safeguard
